This is a try-out of a FabLab-ready kit design for a 2-Servo walking robot. The design is inspired by the lynxmotion kits and the designs by david buckley. The goal for this project is to make all mechanical parts for the servo walker out of 1 A4 size sheet of plywood (or perspex, lexan, delrin,Read more
The simple 2-servo walker (which I hope to use as a fablab-ready robot kit) went through its first paces today. The microcontrollerboard used is an ATmega32.. my ‘ottantotto’s haven’t arrived yet 🙁 The robot walks well, now it’s time to make it turn, avoid obstacles, sit up, make noise, etc… You can see it walkRead more

I’m really enthusiastic about the reprap project. The whole Idea of having a printer that can print functioning parts, just on your desktop is .. well.. cool. The reprap is a machine that can replicate part of its own parts. However, to build one from scratch you get a certain ‘bootstrap’ problem.. Hence you haveRead more
Today this tiny crawler took his first steps! This robot uses 5 small-size RC servo’s and is controlled by a small custom microcontrollerboard using an Atmel ATmega8. This controller board is very minimalistic. No power supply regulator, no crystal, just the controller, some capacitors and pcb edge connectors for directly connecting the servo flat cables.Read more
More details on the mechanics. The frame has been made from the cover of a discarded CD-ROM drive. The frame had been cut using metal scissors. Bras tubes have been soldered to the frame in order to form the middle joint. The whiskers are made from guitar string, mounted to paper-detect switches that had aRead more
Today I managed to kill (what could definitely be.. sure…) the last bugs in the design of the Tchibo Cleaner Robot mod-chip. In fact, it is not only a chip.. it is a tiny PCB that slots in the place of the original ATmega8 controller. On this PCB an ATmega32, 16MHz crystal and Max3232 areRead more
While making a dynamixel library for Processing, I started fiddling around with a simple humanoid head that I constructed earlier (as temporary setup for the soccer Humanoid). This head consists of three AX-12+ types dynamixel servo’s by Robotis, and two Logitech Webcam’s (currently only one used). The control software in Processing controls the head (basicRead more
The Arduino boards mainly use Atmega8 or ATmega168 controllers. For most of the projects and boards I have been working with in the last years, I have been using mega32 (more memory, more IO). In order to make use of the excellent Arduino resources, making my boards Arduino Compatible seems a logical choice. First thingRead more
In the netherlands a lot of webshops have the Tchibo Vacuum robot on on sale at ridiculous discount prices.Read more
